Counting Statistics

Inductively coupled plasma-mass spectrometry (ICP-MS) was used to measure ng/L quantities of uranium in solution. Pneumatic nebulization and ultrasonic nebulization were compared. The spectral integration period was varied to study the effects of counting statistics. Analyte detection at m/z 238 was found to be blank limited. Under optimal conditions (i.e., with the use of ultrasonic nebulization and an 11-s integration period per m/z), uranium detection limits (3 σ) at m/z 234 (not blank limited) were found to be 0.1 ng/L in 18-MΩ water. The uranium detection limit at m/z 234 was 0.5 ng/L when a 2.5-g/L NaNO3 solution was nebulized. Normalized instrument response for uranium in 18-MΩ water agreed well with that in 2.5-g/L NaNO3.

The purpose of this study was to evaluate whether nedocromil sodium benefits urban asthmatic children showing seasonal bronchial hyper-reactivity to ultrasonic nebulization of distilled water (UNDW). A prospective, randomized, placebo-controlled, parallel-group, double-blind study was carried out at the outpatient pulmonology service at a tertiary-care teaching hospital. Twelve children living in Milan, who were 7–17 years of age, who were SPT and RAST-negative to perennial allergens, who were suffering from episodic asthma, and showing seasonal bronchial hyper-reactivity to UNDW during winter, participated in this study. All the children received either placebo or nedocromil sodium, 4 mg every 6 h for 6 weeks. Spirometry and UNDW challenge were done at the following times: day−7; day 0; day 1; day 7; day 14; day 28; day 42. No differences were found in the basal spirometric parameters, which were normal in both nedocromil and placebo groups. Bronchial reactivity to UNDW was found to be significantly decreased in the group treated with nedocromtl starting from day 7. It is therefore concluded that nedocromil sodium can reverse bronchial hyper-reactivity caused by seasonal factors such as cold, viral infections and atmospheric pollutants in children suffering from asthma.
